Does Jeep Wrangler Battery Need Charging When Using Curt Tow Bar Wiring

Question:

Do I need a battery charger with BLU79FR? This looks like a great solution for a 2019 JLU. It is not clear to me if this will use the RV power or if a battery charger is required to be installed in the jeep. Thanks.

Since it will be connected to your motorhome, you do not need any type of battery charger in your 2019 Jeep Wrangler Unlimited when using the wiring kit from Curt:

Kyle - thanks for the quick response! One follow-up question - I realized there may be another need for power. If I use the Demco Stay n Play braking system - would that require a battery charger? Thanks again!

@JT Tow bar wiring kits use the power of the towing vehicle - not the towed vehicle. Supplemental braking systems use the power from the towed vehicle that they are in. The trickle charge being applied to the towed vehicles battery is enough to run it.
